Abstract
The generalized k-connectivity \(\kappa _k(G)\) of a graph G, introduced by Hager (J Comb Theory 38:179–189, 1985) is a generalization of the classical connectivity \(\kappa (G)\) with \(\kappa _2(G)=\kappa (G)\). In this paper, we construct graphs to show that for every pair of integers m and \(n(1<n <m)\) there is a graph with the generalized 3-connectivity n whose line graph has the generalized 3-connectivity m.
